Abstract: The invention relates to a solar pick-up comprising a panel and means associated with this panel, suitable for absorbing the solar radiation and for heating a fluid, wherein said means are constituted by a thin metal foil which covers virtually all the panel and which presents at least one first face exposed directly to the solar radiation, blackened and treated on the surface to pick up the solar radiation and a second face, opposite the first, in direct contact over virtually the whole of its surface with said fluid, said foil transmitting the picked-up heat to said fluid through its thickness.
